As I had guessed... Motortrend.com is now correcting itself and posting what we have talked about at length:

"UPDATE: Our sources have just confirmed that the supercharged V-8 that will power the 2009 Corvette SS/Z07/Blue Devil and the supercharged V-8 that will power the '09 Cadillac CTS-v will be 6.2 liters, not the 7.0-liter as we reported in our July issue. It makes sense in that General Motors was getting the horsepower, but not the torque it wanted from the 427.6 cubic-inch engine. Despite the engine difference, we continue to expect the CTS-v to come with some 600-horsepower when it arrives.
"

NOW everything is coming together... it makes waaay more sense. They will def. stick this engine in the new Camaro Z28 (IMHO), so we can hope for BIG things!

I don't follow...How can GM be putting the top engine of the biggest-baddest Corvette ever built in the Camaro?...I can't see it...

Actually GM only makes one engine. They just tune the engine for MPG or HP through the computer settings. A few computer tweaks and a Impala can do 0-60 in 2.3 seconds...

Really!

Really? I see you drive an Avalanche....do you suppose the guy down the street driving a Cobalt has the same engine as yours, just tuned for MPG rather than HP?

How about the Vette on the other block? Same engine as yours just tuned for....oh wait, the Vette has more HP and more MPG than your Avalanche. But I thought they used the same engine, just tuned for HP or MPG.

Come on man, did you really just say that with a straight face? Please tell us you were joking.

I was going to say something too. But, I knew he just couldn't be serious. I took it as being fesicious (spelling right?). Because in that case, I think I'd just go get my 4th Gen tuned so I could pump out the Z06's 505hp and I'd say screw getting a new car. I've got everything right here! Yeah...I'm pretty sure he's joking.

To the best of my knowledge, in the past GM has kept the Camaro & Trans Am's up to par with it's line of high-end Caddy's (HP wise). For example, Cadillac's NorthStar engine having 300 hp while regular z28's, firehawks & ss's have had 300+.

Maybe it'll never happen but I'm hoping that with Cadillacs involvement, the SS Camaro will get a high-end upgrade. Even if it's a Limited Edition like what Ford's doing with the Shelby GT500.

Really!

In my area of the plant, GM Powertrain St. Catharines, we make the LS2, LS3, LS4, LH6, LSA and that is just the Aluminum blocks. There is also the Cast Iron blocks and engines and the high feature V6 (HFV6) block machining and assembly area. So, in my books, just in our plant alone, that is more than one engine!
I guess if we are not sure about what we are saying, then it is best left unsaid! Maybe he was thinking of toyota who puts the same engine in all their cars from the premium priced lexus on down. But then again, maybe you just pulled one over on us!

HAHA!! OMG! I'm rolling on the floor right now, haha!
Hmm. all better now. If he/you was/are serious (we may have scared him away...) he may have been thinking about the "small-block" designation. And thinking that it meant the same engine black all the way around.

Though it's not like they are really that different. They all have pistons, cylinders, and valves. If you want REALLY different you'd have to go to a wankel (rotary) motor...

In reality now I've been trying to source a new motor for my CJ7 Jeep and all of the used engine guys have been looking at me weird when I say "Which 5.7 Liter is that V8?"... I've heard "they're all the same" so many times. Never mind the difference in complexity between fuel injection and carbs.

I think I've decided to go with a 5.3L like what is in my Avalanche as a few companies are making the computers to allow that kind of install. It is also almost as light as the AMC 258 20 year old six cylinder in there now. Which blows my mind.

GM has always given it's consumers the most interchangable parts on the market all of their engine blocks and trans housings bold up in trucks. parts swap over insanely easy.... that's what made Gm #1 for so long.

They have many engine configurations... very similar blocks but many different parts that go on to make the long block

Here's a bit of trivia. GM has used basically the same bolt pattern for the bell housing for EVERY V8 (small block) and V6 since something like 1958? It's the standard pattern and Cummings diesels (4bt) use that pattern for their adapter plate in the Frito Lay and Wonder Bread box vans.

Remind me what a bell housing is?

And why change something that works? Same deal with the pushrod argument...

1958...hmm. Proves they still do make 'em like they used to, huh?
And all the small blocks share the basic block design.

It would be 1955, and its small block, big block, 90 degree v6(200,229,265), as well as L6 and L4 pushrod engines but not the "W" motors(348, 409) or the 60 degree v6s(2.8,3.1,3.4,3.5,3.9,these share the small bellhousing pattern with the likes of the 3.8 buick and the northstar)
